The SureFire X300-A Ultra WeaponLight has been designed for long guns and handguns, and generates 600 lumens of white light with a TIR lens to produce a tight beam with extended reach and significant surround light. This tactical level light produces more than enough light to overwhelm an aggressor's dark-adapted vision for a full 1.5 hours per set of batteries. This light features ambidextrous switching with one finger control of momentary-on via press activation or constant on by flipping up or down.
